Description

  The present invention relates to a water-stopping structure for a fore edge portion of a winning frame that appears around a sash frame at a joint between a vertical frame and a horizontal frame of the sash frame.

  Conventionally, since the vertical frame and the horizontal frame constituting the sash frame are won or lost at the joint portion, the cross-sectional edge portion of the winning side frame appears in the waterproof processing portion between the exterior members around the sash frame. The cross-sectional edge of the winning frame that appears in this waterproofing part is usually waterproofed with regular and irregular sealing materials, but most of it is a void, so waterproofing performance only with the sealing material is demonstrated. What is done is limited to only the cross-section (cut surface) excluding the voids in the cross-sectional edge of the frame. For this reason, conventionally, the cross-sectional edge portion of the winning frame including the gap is generally closed with a fixed lid member or the like.

JP 2001-65239 A

  In general, the following two are well known as structures for closing the above-mentioned frame edge portion on the winning side with a fixed lid member.

  1. There is a method in which the lid member is slightly smaller than the inner shape of the frame fore edge, and the lid member is fitted into the edge of the frame from above. In this case, since there is no water-stopping performance between the lid member and the frame edge, the water-stopping performance can be reduced by placing a separate sealing material between the lid member and the frame edge as needed. Ensuring performance. For example, in Patent Document 1, a caulking material (sealing material) is preliminarily filled in a rigid frame hollow portion to be closed (a gap portion of the frame edge portion), and then a closing member (lid is covered with the hard frame hollow portion filled with the caulking material. The water stoppage performance is secured by pushing in the member. However, this method may cause compatibility with the sealing material between the sash frame and the exterior member, construction failure of the joint portion due to a shift in the placement time, and the like. In addition, troublesome work is required by placing an irregular sealing material separately.

  2. A method in which the lid member has the same shape as the cross-sectional shape of the frame edge portion, and a screw hole for fixing the lid member is provided in the cross-section of the frame edge portion so that the edge portion of the frame is covered with a fastening member such as a screw. There is. In this case, the water-stopping performance of the lid member and the frame edge portion can be ensured by setting a fixed water-stopping material for the lid member. However, since the lid member has the same shape as the cross-sectional shape of the frame edge portion, the thickness of the lid member is exposed (projected) from the periphery of the sash frame, and the aesthetic appearance is impaired. Further, since the lid member is exposed to the outside together with the sash frame, the lid member needs to be durable (particularly weather resistance), but it is expensive to make the lid member highly durable. In addition, since an acute corner portion is formed at the joint portion between the protruding lid member and the sash frame as described above, this portion causes a pinhole in the sealing, and the joint portion between the lid member and the sash frame is formed. There is a possibility that sufficient waterstop cannot be secured.

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to win the frame edge portion that appears around the sash frame at the frame joint portion without taking much labor and without losing aesthetics ( It is to secure the water stop performance of the gap portion and improve the reliability of the waterproof performance with the exterior member around the sash frame.

  In order to achieve the above object, the water stop structure of a representative sash frame fore edge portion of the present invention stops water at the fore edge of the winning frame that appears around the frame at the joint between the vertical frame and the horizontal frame of the sash frame. In this case, the inner shape of the winning side frame edge portion is tapered toward the outdoor side and the inner corner portion of the outdoor side is formed in an arc shape, and is slightly smaller than the inner shape of the winning side frame edge portion. A lid member having an elastic water stop material at an edge of the flat plate portion that has a flat plate portion in shape and faces at least an inner surface of the winning frame edge portion; It is characterized by being pressed and fixed toward the tapered outdoor side.

  According to the above structure, the water stop performance of the winning side frame edge portion (gap portion) appearing around the sash frame at the frame joint portion is ensured without taking much time and without deteriorating the aesthetics, and around the sash frame. The reliability of waterproof performance with the exterior member can be improved.
